Question 1

How are sea turtles are affected by climate change?

Answer 1

• loss of nesting branches and coastal habitat
• decrease in hatching success from increase in temps
• change in ocean currents from increase in temps
• shoreline erosion

Question 2

How are polar bears are affected by climate change?

Answer 2

• loss of food source
• habitat declines due to thinning ice
• ringed seals need the ice for raising pups

Question 3

How are coral reefs are affected by climate change?

Answer 3

they experience coral bleaching
caused by ocean temperature, runoff and pollution,
overexposure, and extreme low tides.

They have symbiotic
relationships with algae that depend on certain temperatures for photosynthesis, which is what gives the coral its color.
